How should businesses of different sizes decide how much to invest in SEO and how to carry it out?

Whether a business should invest in SEO should depend not just on company size, but on brand visibility, keyword competition, available staff, and business goals. Businesses in low-competition industries can consider improving their websites and content themselves; small businesses that need to reach nearby customers can focus on local search; and large businesses that already have visibility can review whether their existing content aligns with their products and conversion goals. Outsourcing can provide additional resources for execution, but it cannot replace the business’s role in communicating about its products and services, nor does it mean orders will naturally increase.

Identify the visibility you need before deciding whether to invest

An article by Da Vinci Digital Technology suggests that small and medium-sized businesses with lower brand awareness can use non-branded keywords to reach customers who do not yet know them. For example, someone searching for “bubble tea recommendations” could find relevant content without first knowing a shop’s name. This is a different investment objective from gaining visibility in searches for an existing brand name.

SEO is not the only option, however. The article also suggests considering paid search ads directly if keyword competition is low and the cost per click is modest. This is a conditional recommendation, not a suggestion that all small businesses should choose advertising. Nor does it support the opposite claim that organic traffic is necessarily more cost-effective.

When resources are limited, narrow the scope rather than buying a full-service package right away

• Low-competition or niche industries: The Da Vinci article suggests starting with an appropriate website structure and content managed in-house, without necessarily hiring an expensive consultant. This assumes the business actually has the ability to maintain its website and produce content; being small alone does not make a do-it-yourself approach suitable.
• Shops serving nearby customers: Using a small bakery as an example, the Semrush article explains that a consultant can help reach nearby potential customers through local SEO. The initial scope need not extend to a broad market.
• A lack of staff for ongoing execution: Semrush suggests that agencies generally have the resources to manage content strategy over the long term. When comparing options, businesses should distinguish between a need for strategic judgment and a need for ongoing production and maintenance.

Large businesses should check whether their existing visibility aligns with their products

A well-known brand does not necessarily have no SEO work to do. The Da Vinci article focuses more on branded search and suggests that well-known brands may not need to invest. Semrush presents another scenario: businesses that already have visibility can shift their focus to making better use of existing traffic and improving conversion rates.

Semrush reports that HoneyBook shifted toward product-focused campaigns in 2021 and assessed keyword difficulty and backlink opportunities. Subsequently, visibility for its target keywords increased by 7%, while the average ranking of its newer articles rose by 30 positions. This is a specific historical case. It does not prove that any single measure caused all of the growth, nor does it guarantee results that other businesses can expect.

Before outsourcing, define the work the business must still handle

As the Da Vinci article points out, consultants can analyze industries, competitors, and keywords, and may also help with articles and the website experience. Businesses must still contribute to communicating about their products and services. Evaluating approaches to execution therefore involves more than comparing who promises more rankings. It also requires clarifying who will provide product information, who will maintain the content, and whether that content helps visitors understand the services and take the next step.
